CHARLES A. OLSON, OF JAMESTOVIN, NEW YORK.

NRENCH.

Application filed April 29,

T0 aZZ whom it may concern:

Be it known that l, CHAnLns A. Onsorz, a

citizen of the United States residing at Jamestown, in the county of Chautauqua, State of New York, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in wrenches.

One object of the invention is to provide a wrench which can be manufactured at alower cost than the drop forged wrenches now made, and with fewer and simpler operations.

Another object is to provide a wrench which is made from sheet metal, and is of such construction that it is strong, durable, and eflicient in operation.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawing. 1

In the drawing:

Figure 1 is a side elevation of a wrench made in accordance with the invention.

Figure 2 is a vertical transverse sectional view through the handle, on the line 22 of Figure 1.

Figure 3 is a longitudinal central sectional view through the wrench, on the line 83 of Figure 1.

Figure 4 is a vertical longitudinal central sectional view through the wrench, in a plane parallel to that of Figure 1.

Referring particularly to the accompanying drawing, 10 represents a strip of sheet metal, of suitable length and thickness, and slightly tapering toward one end. A pair of metal plates 11 are welded to the opposite side faces of one end of the strip 10. The lastnamed end of the strip 10 is cut out angularly to form the stationary jaw 12, of the wrench, and formed vertically in the end of the device, above the jaw 12, is a circular bore 13. At the upper end of this bore 13 there is formed a recess 14 for the reception of the head 15 of the screw 16. ltemovably Specification of Letters Patent.

1921. Serial No. 465,432.

engaged through the upper portion of the strip 10, and communicating with the bore 13, is a screw pin 17. which engages beneath the head. of the screw to prevent movement thereof, longitudinally in the said bore.

The movable jaw of the wrench consists of a central plate 18, on the opposite side faces of which are welded the plates 19. he plates 18 and 19 are provided with the upper curved face 20, in the manner of the ordinary wrench jaw. The stationary jaw 12 has its lower face curved, as shown at 12'. The inner or rear ends of the intermediate plate 18 is formed with an internally threaded tubular member 21, which is arranged to travel longitudinally in the bore 13, and receive the screw 16 therethrough.

The opposite sides of the walls of the recess 14 are cut away, as at 22, to permit the head of the screw to be grasped by the oper ator, for rotation. Upon rotation of the screw 16. as will be clear from the drawing, the movable jaw will be moved toward and away from the stationary aw.

A strip of metal tubing 23 has one side longitudinally slotted to receive the edge portions of the strip 10, said tube being welded to the strip. Th tubing serves to reinforce the strip 1 and prevents lateral bending of the same. It will be noted that the edge portions of the strip 10 are notched to insure of a better and firmer attachment of the tubing.

It will further be noted that the plates 11 extend rearward on the sides of the plate 10 to such. distances as to insure a strong and rigid construction.

By the present construction, the wrench can be made with less labor, and with the use of less operations or machines. The re sult will thus be the production of a strong and durable wrench. at a cost which is less than other wrenches of this type.

What is claimed is:

A wrench body comprising a flat metal portion including a shank and a head, the outer end of the head being oblique to the transverse axis of the body, a pair of plates secured on opposite sides of the head and each having an outwardly bowed rib extending transversely thereof and in parallel re lation to the oblique end of the head, a portion of the outer end of the head extending longitudinally beyond the oblique face, each 01": the said plates having an extension corresponding to the extension of the body and being secured to opposite sides thereof and a semi-tubular strip secured to the marginal edges of the shank of the body and around the outer end, the ends of the strip resting against the side plates.

In testimony whereof, I afiix my signature in the presence of two Witnesses.
